ATTACHMENT FOR WRIST-WATCHES.

Specification of Letters Patent.

Patented Sept. 7, 1915.

Application filed January 30, 1915. Serial No. 5,283.

To all whom it may concern.

Be it known that I, THOMAS F. HATHA- WAY, a citizen of the UnitedStates, residing at Elgin, in the county of Kane and State of Illinois,have invented certain new and useful Improvements in Attachments forHist-Watches, of which the following is a specification.

The present invention relates to an attachment more particularlyintended and adapted for use in connection with wrist watches, and forthe purpose of serving as a means for connecting one end of the braceletor strap used in conjunction with these watches to the body of thewatch.

The objects of the invention are to provide an attachment of thecharacter described, in the form of a ring post which, in conjunctionwith the ordinary pendant construction, will allow of a turning movementof the watch about its longitudinal center so as to permit of theexposure of either the face or back of the watch as may be desired; toprovide a guard or shield arranged in proper relation to the ring postto prevent it from becoming broken, bent, or injured by accidentallystriking against some extraneous surface; to so construct the ring postas to permit of its connection to the watch body without the use ofscrews, nuts, or similar devices which might become loose in use andpermit a disconnection: and to provide an attachment considered as awhole which is economical and simple of construc tion and easy ofapplication to the watch body, and ornamental or finished in appearance.

The invention further consists in the features of construction andcombinations of parts hereinafter described and claimed.

In the drawings: Figure 1 is an elevation showing a watch equipped withthe attachment of the present invention and the bracelet or strapconnected to the watch; Fig. 2 is an enlarged section oi one end of thewatch showing the ring post of the present invention in place; Fig. 3 isan elevation of the ring post of the present invention prior to itsapplication to the watch body; and Fig. i is a detail in perspective ofthe guard or shield member as initially constructed and prior to 1tsapplication to the watch body.

Referring now to the drawings, the attachment which, as a whole,consists of the variety, although, of course, this is not to be deemed alimitation or restriction upon the scope of the present invention. Theattachment itself comprises a ring post 3 chambered or recessed at itsinner end for a short distance inward, as shown at 9, and the stem 8 ofthe post has secured thereto or formed integral therewith a ring 10. Thepost is of a size to permit it to have a turning or pivotal fit within ahole or opening 11 in the body of the watch, and after being placed inposition, the inner end of the post is upset or flanged as indicated bythe numeral 12, by means of any desired or suitable tool. When this hasbeen done, the post will be securely attached to the body of the watchin a firm and efiicient manner. The post thus made and attached has nothreaded parts or nuts for holding it in place, thus eliminating anydanger of its becoming disconnected by loosening of the threaded partsor nuts. When attached in the manner described, the post will have afree turning movement in the body of the watch. The end 13 of thebracelet or chain is attached to the ring 10 by a spring snap or anysuitable means, and when both ends of the bracelet chain or strap areattached, as in Fig. 1, the bracelet will be attached at one end to thependant 6 which has the usual pivotal movement, and at its other end tothe ring 10, the stem 8 of which also has a pivotal movement; and thesepoints of attachment being diametrically opposite one another the bodyof the watch is permitted a free turning movement about its longitudinalcenter, whereby the face or back of the watch can be exposed as desired.

I provide a guard or shield member 14: which, when attached in position,acts as a protector for the ring post to prevent it from being struckagainst some extraneous surface, and thereby bent, broken, or injured.It also serves as a means for ornamenting or giving a finishedappearance to that side of the watch body to which it is attached,whereby, if desired, the watch may be used as a chatelain or belt typewatch in place of the wrist type.

For the purpose of simplifying the manufacture, as well as securingeconomy in the process and facility in the attachment of the guards orshields to the watch, I initially form the protecting member H of asingle piece, by striking or cutting the same out of metal sheet, orother source of raw supply. The member is brazed or otherwise attachedto the body of the watch along the surfaces 15 in its initial orintegral condition. After being so attached, the central portion 16 iscut out as indicated by dotted lines in Fig. 4. A hole is then drilledthrough the watch case to the interior, and the ring post inserted inplace and its inner end spread or upset as already explained. It Will beobvious that, if the edge of the watch be rubbed against some surface,moving toward the ring post from either side, the guards-or shields atthe one side or the other will shunt or deflect such surface away fromthe post, so that it will not be broken, bent, or injured. Y

I claim:

1. In combination with a watch body of the character described, anattachment comprising a stem having a recess in one end extendingpartially the length thereof, a flange formed at the extremity of saidrecessed end, a ring at the opposite end of said attachment, and guardmembers attached to the watch body and arranged at each side of thering, substantially as described.

2. In combination with a watch case, a shield, guard or protecting piececomprising a single piece of metal arranged with companion orcomplementary end portions positively secured directly to the curvedouter periphery of the watch case, and a central portion raised as toits outer surface, substantially as described.

3. In combination with a watch case, a shield, guard or protecting piececomprising a single piece of metal arranged with companion orcomplementary end portions positively secured directly to the curvedouter periphery of the watch case, and a central portion ofconcavo-convex formation, substantially as described.

4. In combination with a watch case, an attachment composed of a singlepiece of metal arranged with companion or complementary end portionspositively secured directly to the periphery of a watch case, a centralportion and the inner face of the central portion being raised withrespect to the inner faces of the end portions whereby said centralportion is out of contact with the periphery of the watch case when theattachment is secured thereto, substantially as described.
